Hello, I have a question for multiplus experts that i couldn't find any clue on Victron community or on the web.
After working fine for 2 weeks after installation my multiplus* stopped working with all led on solid (all 8 leds). No communication with VE.configure possible even if my MK2 interface is detected.
I checked inside the multiplus as much as i could: no component burned, i changed the microprocessor main board with a new one with no success, all mosfets on the big aluminum heat sink are ok, visually everythink looks ok.
I guess that all 8 leds on solid in an error code but no clue given on the Victron manual.
This is the first time i have a problem with multiplus, i have two more multiplus on my system which have been working fine for 9 years.
Thanks for any kindly help the community can provide, i would hate to throw my multiplus in the trash!
* note: it is a used one bought on Le Bon Coin (old microprocessor 1922143)
